<P>PROBLEM TO BE SOLVED: To develop a positive electrode material capable of stably inserting/desorbing a plurality of ions having a positive charge such as lithium ions, more specifically, to provide a positive electrode material for a storage battery, having excellent ion conductivity, safely and stably developing high energy density (high capacity density and high charge/discharge potential), and capable of achieving reduced weight and compactness of a storage battery or the like, and to provide a storage battery manufactured using the positive electrode material. <P>SOLUTION: The positive electrode material includes a compound represented by the following general formula (1): A<SB POS="POST">[n+1]</SB>B<SB POS="POST">[n]</SB>C<SB POS="POST">[3n+δ]</SB>...(1). In the formula, A represents at least one element selected from the group consisting of H, Li, Na, K, Rb, Cs, Ca, Sr, Ba and La, B represents at least one element selected from the group consisting of Ti, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Zr, Nb, Mo, Sn and Ta, C represents at least one element selected from the group consisting of O, F, S and Cl, n represents an integer of 1-10, and δ represents a number satisfying 0<δ≤1. <P>COPYRIGHT: (C)2013,JPO&INPIT |
